DeWalt DC927KL Hammer Drill

Long-Term
DeWalt says its new 18-volt nanophosphate lithium-ion batteries can endure 2,000 charging cycles — three to four times the number you can expect from a similarly sized nicad pack. Though they're also compatible with older DeWalt tools, the batteries are included with the company's new DC927KL 1/2-inch three-speed hammer drill. In addition to the tool and two batteries, the $370 kit contains a one-hour charger and a case. DeWalt, 800/433-9258. www.dewalt.com
